I brought home a stray and she had three kittens under my bed. She's been taking excellent care of them and they are starting to explore my room. There are 2 whites ones and one black one. To be honest, I don't spend all that much time with them (I'm a single mom, college student and I'm interning as a paralegal at a law firm). Anyway, I don't have the best memory and I haven't kept notes or anything but I feel like the two white ones are more active. I have definitely seen the two white ones walking on all fours. The white ones seems like they're always together and explore more. The black one seems to sleep more. Anyway, I just went in my room and I was petting the black one and he started to move around. I noticed that it seemed like he was half crawling and half walking. His rear was all the way up in the air (standing up on his hind legs) but his front paws, legs, and chest remained on the floor. He doesn't appear to be able to bear any weight on his front legs.
